Misinformed dimensions
This product misinformed me of size. It’s 47.235” in length not 48” as advertised. This is just another means of manufacture cheating customers with false information. I did not return as I was just moving into home. I was also in a hurry to finish the installation since I bought three of these not knowing the truth. You can make your own choice but I needed 48” and paid for 48” and got shorted. I used the shipping box to make an template to install brackets that manufacture did not provide.

One out of the four shelves was badly bowed
Exactly what I was looking for but the reason for only three stars is thatone out of the four shelves is extremely bowed, but I only needed three so I just kept them. The quality on the other three is good they are a lightweight wood and anchored to the wall. Well, they seem pretty solid.
